Henk and others, can you comment on how this relates to FIDO, Android Attestation, ARM PSA Token and such?

It seems that a decision has to be taken as to whether this is:
- THE generic interaction model for all of RATS in which case FIDO, Android and such have to fit into it
- One interaction model specific to a subset of RATS use cases

I did a quick read and it seems like FIDO, Android and such could fit. But it seems a commitment one way or the other is needed up front. If it is THE model, then the work to make sure it is fully generic needs to be done. People (not just me) will have to review it to see if it fits all attestation use cases. If it doesn’t there will be writing to do.

Right now it seems framed as THE interaction mode (abstract, introduction sections). Are the authors committing to this as THE Rats interaction model?

I think this needs to be clear before the document is adopted.

If you have reservations for documenting interaction models, or for such a document to be a standalone draft to describe all of them please respond to the mail list and provide rationale for your concerns.
